This was the first game I ever worked on as a programmer. It was
a very interesting experience, because much of the basic engine
code that ran the game ended up being based on a prototype psuedo-3D
engine I built on a Sega Genesis. The original design included
three different modes of play - a top down, a side scrolling,
and a 1st person POV. It became clear that the design
was much to big. However, just as everyone was trying to figure
out where to go next, I finished my prototype for the 1st
person POV, and the new design ended up being based around it.

I also ended up doing many of the dinosaur behaviors, and the
Galli, Dilo, and 75% of the Tri Territories. I even managed to
play at being an artist in a few cases... Originally, the raptor
caves had much less on the foreground layer, but I found a way
to include more. However, since the artists were busy, I spent
several late nights cutting the foreground layers out myself.
I also added the frog to the fishing Gallimimus animation (all
ten pixels of it).

Perhaps the best part of the project, however, was meeting Dr.
Robert Bakker, one of the foremost paleontologists in the world.
He not only helped the artists develop the dino animations, but
even appeared in the game. Dr. Bakker has several interesting
books, including The Dinosaur Heresies (about the changing
views of dinos from slow reptiles to warm blooded fast moving
animals), and a wonderful novel (Raptor Red) written from
the point of view of a velociraptor.

Below you can find a complete map of the game, with the locations
of all the game objects, as well as most of the game cheats and
several really good easter eggs.

In INT1 (the first game location, with the crashed helicopter),
use a rock on the far shore in the south quadrant. When you find
the right location, you will get a bell. This enables the 2nd
joypad.

The 2nd joypad functions are:

START - load the node jumper (allows you to go to any location
in the game)

C btn - gives you all the useful objects for the location you
are in

To get an infinite supply of gas grenades

Go to the Visitor Center, in the hallway facing the door to Muldoon's
Office (VC4). Use the Rex-CD on the card reader to the right of
the door. When you enter Muldoon's Office, the locker will never
run out of gas grenades.

To get an answering machine message

Go to Wu's Office (VC3). Use the pliers on the answering machine
on the desk, and it will play someone's final phone call .

To see a T-Rex vs. Triceratops battle

This easter egg was my personal contribution to the game. One
of the artists had made a little animation of a T-Rex chasing
some Gallimimus that was to go into GAL4 (the Galli Old Nest).
However, we decided not to put it in, because the T-Rex didn't
look like the other Rex anims in the game. So I shrunk down some
of the Triceratops anims and used them to create the classic dino
battle. Goto the Galli Frog Pond (GAL5), and use the wire cutters
on a branch sticking out of the left side of a tree in the south
quadrant (you will get a bell if you find it). Then backtrack
to the Galli Old Nest (GAL4), and you will see the battle.

NOTE: this will not work after the Biosyn helicopter arrives on
the island (because GAL4 then becomes the final battle location).
It will also not work unless you have been to GAL4 at least once
before (so the galli herd can run by).

To See the Visitors Center Explode

Goto the Visitor Center Control Room (VC2), and use a rock on
the computer screen. You will then automatically walk back down
the stairs, and the Visitor Center goes boom around you! I think
the original game design included this video as part of the game,
but we dropped it for some reason. However, the video had already
been made, so one of the other programmers stuck it in.
